Hi folks, I’m struggling a bit with writing queries in the MongoDB shell. Coming from a SQL background, I keep thinking in terms of JOINs and WHERE clauses, but MongoDB does it completely differently. I tried using find() on a collection, but I get overwhelmed with all the syntax options like projections and filters. Does anyone have a simple approach or a tutorial that breaks down these commands without assuming you’re already an expert? Bonus points if it includes examples that I can try in my own test database!

I hear you! Switching from SQL to MongoDB queries can feel like suddenly having to speak a new dialect overnight. I remember spending hours just trying to figure out how find() really works and how to filter documents without getting lost in the curly braces. What saved me was a really detailed tutorial that explained not just the commands, but also the reasoning behind them. It starts with the basics like db.collection.find({}), explains projections, and even dives into updating documents step by step. Here’s the link I used: https://hostman.com/tutorials/how-to-use-the-mongodb-shell/ Going through it slowly, experimenting as I read, made everything click eventually. And a little tip: try using sample data from a project you actually care about—it makes learning way less boring!
